@GiacomoSansoni yes it's true that HKSAR is now entirely under the laws of the mainland. If they were doing something that's illegal then they would be shut down, it's that simple.
@yogthos Well, no, it's not true that the HKSAR is now entirely under the laws of the rest of the country. The new national security law introduces new, severe restrictions to freedom of speech, but the HKSAR in theory is still a different system within the same country, so it makes sense Lausan may still find there more freedom than in other parts of the PRC. This is how the collective itself talks about the national security law: https://lausan.hk/2020/hong-kongs-new-era-of-terror/
